Plugged in, not charging....

I have a one year old Dell 1525 giving me a problem with a "plugged in, not charging" message.

The bios setup screen shows battery condition and it says "moderate". The bios setup recognizes the charger as well.

The battery does charge (displays "plugged in, charging") but only to 48%, that's when it switches to the "not charging" message.

Does this sound like it's just a bad battery causing this?

Thanks in advance!

Do you keep said laptop plugged in constantly? What happens is after awhile, if a laptop is kept constantly plugged in, it creates a "memory" on the battery, and theres nothing much you can do about it. So my guess is its likely the battery, is said laptop still under warranty by any chance?

The following article explains why the memory problem occurs, and what you can do about it.

Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem. Letting the battery run down to the cut-off point in the equipment will do this. If ignored, the fuel gauge will become increasingly less accurate.

Thanks for the info. The laptop is hardly ever unplugged for more than an hour or two. And no, the 1 year just expired.

The point of the excerpt that I posted is that in order to regain that full battery capacity is to discharge the battery completely and then charge it.

Thankyou for explaining that better for me Dc3. I hope this solution works, its never worked for me in the past but Ive mostly been working with older laptops.
